CVE-2015-2721 
Karthikeyan Bhargavan discovered that NSS incorrectly handles state
transitions for the TLS state machine. A man-in-the-middle attacker
could exploit this flaw to skip the ServerKeyExchange message and
remove the forward-secrecy property.

CVE-2015-2730 
Watson Ladd discovered that NSS does not properly perform Elliptical
Curve Cryptography (ECC) multiplication, allowing a remote attacker
to potentially spoof ECDSA signatures.");
